[lbackup-discussion] volume paths confusion

[Scott Haneda]

I am not sure how to tell the version of lbackup I am using, but I did  
just download it today.  I am using:

$rsync --version
rsync  version 3.0.6  protocol version 30

It is patched as best as I can tell.

Today was my first effort to use the scripts.  I am trying to backup  
one boot volume to a second volume. Two different distinct drives.

First I did this
  backupSource="/Volumes/boot-drive"
  backupDest="/Volumes/secondary/backups/daily"

This backup happened in seconds.  I would guess that all it did was  
make some links.  So this tells me, I believe, that if the primary  
drive goes down, I have a useless backup, is that correct?

Now I am doing this:
  backupSource="/"
  backupDest="/Volumes/secondary/backups/daily"

This is taking a considerable amount of time, so I suspect this is  
what I want.  Can I get some clarification on how this works with paths?

A second backup scenario, is to copy one directory from one drive, to  
a directory on another drive. On this one, I used full paths, and it  
took a while, so I feel relatively confident that it made actual data  
copies:

  backupSource="/Volumes/secondary/MailStore"
  backupDest="/Volumes/boot-drive/Users/me/backups/mail-rotations"

Why did this one work correct, and the first one did not?  What  
command would I use in the shell to tell which files are real files,  
and which ones are just hard links off to other files?

Here is the log from the first backup, where I am trying to clone the  
boot volume to a second source:

As you can see, not a lot happened.

Here is the log from the second scenrio, which had what looks to me to  
be a correct backup
